The increasing demand for the banana requires the availability of seedlings, while conventional cultivation is unable to produce healthy, disease-free seedlings in a short time and large amount. In vitro culture is considered to be able to handle the constraints of the conventional seed supply. The purpose of this study was to determine the effect of foliar fertilizers on in vitro multiplication of barangan bananas. The method used was a single factor of Completely Randomized Design (CRD), the addition of leaf fertilizer consisting of five levels of media treatment, media MS (control), and 0.50 ml L-1 (p1); 0.75 ml L-1 (p2); 1.00 ml L-1 (p3); 1.25 ml L-1 (p4); 1.50 ml L-1 (p5) of leaf fertilizer media repeated five times. The data were analyzed with Analysis Variance then followed by Duncan Multiple Ranged Test of 5%. The results showed MS media still gave the best results compared to other leaf fertilizer media. Meanwhile, the leaf fertilizer media used in this study still gave good results on the initial time of buds appearance (p3 treatment), the number of shoots and the number of leaves in the p5 treatment, as well as the height of the plant in the p4 and p5 treatments. Therefore, the leaf fertilizer can be used to substitute MS media

The fact that currently clearing forests is still using burning on agricultural land in general and especially on peat soil that is feared to experience underground burning is difficult to overcome and cause many losses. The development of corn on land without burning on peat soil is a solution for the community in maintaining ecosystem sustainability. The explanatory research is directed at testing hypotheses and following research objectives. Data collection by interview and questionnaire to 60 respondents were corn farmers on peat soil. The average difference test is used in explaining the difference in yield between the two methods of planting on peat soil. The results found that there were significant differences in the application of corn cultivation on peat soil without burning compared to the traditional method on the variables fertilizer, pesticide, business costs, and yields. In contrast, the planting area variable had no significant difference.

Colchicine-induced mutation is one of the methods that can be employed to increase plant genetic diversity. This study aimed to determine the effect of colchicine on the performance and genetic parameters of MV3 generation of Plectranthus amboinicus (L.). This study was conducted at the Laboratory of Agricultural Seed Management, Plantation Research and Development Center, from June 2018 to June 2019. Nodes and shoots were used as explants. Mutation induction was performed using colchicine at concentrations of 0%, 0.02%, 0.04%, and 0.06%. Explant regeneration and subculture were done on MS0 medium. The number of plantlets yielded were 59 (0% concentration of colchicine), 60 (0.02%), 81 (0.04%), and 80 plantlets (0.06%), respectively. Results indicated that colchicine-induced mutation in an in vitro culture was able to generate high genetic diversity in both quantitative and qualitative characters of the plantlets. At the concentration of 0.04%, colchicine produced the highest frequency of putative mutants (28.4%). Genetic parameters in MV3 generation of P. amboinicus plantlets showed that five quantitative characters, i.e. plantlet height, number of leaves, number of shoots, leaf length, and number of roots had high heritability values at a concentration around the LC50 value (0.0275%).

This study investigated the effect of different cultivation methods on the rhizome yield of Java turmeric. Different fertilizer treatments(none, organic, inorganic, and semi-organic fertilizer), three groups of rhizome seed size (small (50–80 g), medium (100–150 g), and large (200–250 g)) and three groups of harvesting age (eight, ten, and twelve months after planting) were evaluated in a split plot design experiment. Results show that large rhizome seed size together with organic fertilizer treatment increased secondary rhizome production, yielding the highest number, weight and diameter. As high levels of starch in the primary rhizome are crucial for growth of the plant, the use of large rhizomes for propagation is indicated in Java turmeric cultivation. The highest weight and number of primary rhizomes were yielded when plants were harvested twelve months after planting.

The increasing demand for the banana requires the availability of seedlings, while conventional cultivation is unable to produce healthy, disease-free seedlings in a short time and large amount. In vitro culture is considered to be able to handle the constraints of the conventional seed supply. The purpose of this study was to determine the effect of foliar fertilizers on in vitro multiplication of barangan bananas. The method used was a single factor of Completely Randomized Design (CRD), the addition of leaf fertilizer consisting of five levels of media treatment, media MS (control), and 0.50 ml L-1 (p1); 0.75 ml L-1 (p2); 1.00 ml L-1 (p3); 1.25 ml L-1 (p4); 1.50 ml L-1 (p5) of leaf fertilizer media repeated five times. The data were analyzed with Analysis Variance then followed by Duncan Multiple Ranged Test of 5%. The results showed MS media still gave the best results compared to other leaf fertilizer media. Meanwhile, the leaf fertilizer media used in this study still gave good results on the initial time of buds appearance (p3 treatment), the number of shoots and the number of leaves in the p5 treatment, as well as the height of the plant in the p4 and p5 treatments. Therefore, the leaf fertilizer can be used to substitute MS media

The fact that currently clearing forests is still using burning on agricultural land in general and especially on peat soil that is feared to experience underground burning is difficult to overcome and cause many losses. The development of corn on land without burning on peat soil is a solution for the community in maintaining ecosystem sustainability. The explanatory research is directed at testing hypotheses and following research objectives. Data collection by interview and questionnaire to 60 respondents were corn farmers on peat soil. The average difference test is used in explaining the difference in yield between the two methods of planting on peat soil. The results found that there were significant differences in the application of corn cultivation on peat soil without burning compared to the traditional method on the variables fertilizer, pesticide, business costs, and yields. In contrast, the planting area variable had no significant difference.

Colchicine-induced mutation is one of the methods that can be employed to increase plant genetic diversity. This study aimed to determine the effect of colchicine on the performance and genetic parameters of MV3 generation of Plectranthus amboinicus (L.). This study was conducted at the Laboratory of Agricultural Seed Management, Plantation Research and Development Center, from June 2018 to June 2019. Nodes and shoots were used as explants. Mutation induction was performed using colchicine at concentrations of 0%, 0.02%, 0.04%, and 0.06%. Explant regeneration and subculture were done on MS0 medium. The number of plantlets yielded were 59 (0% concentration of colchicine), 60 (0.02%), 81 (0.04%), and 80 plantlets (0.06%), respectively. Results indicated that colchicine-induced mutation in an in vitro culture was able to generate high genetic diversity in both quantitative and qualitative characters of the plantlets. At the concentration of 0.04%, colchicine produced the highest frequency of putative mutants (28.4%). Genetic parameters in MV3 generation of P. amboinicus plantlets showed that five quantitative characters, i.e. plantlet height, number of leaves, number of shoots, leaf length, and number of roots had high heritability values at a concentration around the LC50 value (0.0275%).

Informasi mengenai perkembangan penyakit tanaman lada di area centra produksi lada yang jarang diperbaharui. Penelitian ini dilakukan untuk mengamati dan menentukan kejadian dan keparahan penyakit tanaman lada menggunakan metode purposive samping. Hasil penelitian ditemukan 3 jenis penyakit yang menginfeksi tanaman lada di Kabupaten Bangka Selatan, yaitu penyakit kuning, busuk pangkal batang dan kerdil virus. Tingkat kejadian dan keparahan penyakit relatif lebih tinggi terjadi di Kecamatan Tukak Sadai. Kejadian penyakit kuning lada, penyakit busuk pangkal batang, dan penyakit virus berkisar 3,33-90,48 %; 43,70 %; dan 12,5-100 %, secara berturut-turut. Keparahan penyakit busuk pangkal batang mencapai 43,11 % dan penyakit virus berkisar 4,58-59,57 %. White pepper production is not in line with the government's extensification and intensification efforts, these are due to disease infection in the pepper plant that tends to increase. Information about disease progression of black pepper plants in production center areas is rarely updated. This research was conducted to observe and determine incidence and severity disease of the black pepper plantations by using the purposive sampling method. The results of the study found three types of disease that infected on black pepper plantations in the South Bangka Regency, namely yellow disease, stem rot disease, and viral disease. The incidence and severity disease are relatively higher in the Tukak Sadai District than others. The incidences of yellow disease, rot stem disease, and viral disease about 3,33 to 90,48 %; 0 to 43,70 %, and 12,5 to 100 %, respectively. The severity of rot stem disease until 43,11 %; and viral disease about 4,58 to 59,57 %.

This study investigated the effect of different cultivation methods on the rhizome yield of Java turmeric. Different fertilizer treatments(none, organic, inorganic, and semi-organic fertilizer), three groups of rhizome seed size (small (50–80 g), medium (100–150 g), and large (200–250 g)) and three groups of harvesting age (eight, ten, and twelve months after planting) were evaluated in a split plot design experiment. Results show that large rhizome seed size together with organic fertilizer treatment increased secondary rhizome production, yielding the highest number, weight and diameter. As high levels of starch in the primary rhizome are crucial for growth of the plant, the use of large rhizomes for propagation is indicated in Java turmeric cultivation. The highest weight and number of primary rhizomes were yielded when plants were harvested twelve months after planting.
